Further Information

Hole 7

Hole 7 on the Cascabel concession was drilled at the Alpala porphyry Cu-Au prospect (Figure 1).

Hole 7 (located at 797078.72 UTME, 83303.33 UTMN and 1757.0m elevation, Azimuth: 220°, Dip: -85°) was terminated on July 25^th at a depth of 1672.76 metres (end of hole or EOH) and drilled along the southwest margin of a large magnetic body that was recently defined by Magnetic Vector Inversion (MVI) modeling which is one of the most advanced and sophisticated modeling technique available (Figures 1 and 2).

Extensive intersections of copper and gold mineralization were encountered in Hole 7, and these intersections are tabulated in Table 1 below.

The bulked intersection of 958m grading 0.40 % copper and 0.17 g/t gold is interpreted to reflect mineralization located along the margins of the recently modeled Central Magnetic Feature (Central Zone) whose lateral dimensions are around 1100m long by 500m wide at a depth of 800m below surface (Figure 1), and extending vertically for approximately 800m from this depth. The 958m intersection is a very long intersection of continuous mineralization located along the margin of the MVI magnetic anomaly, and bodes very well for lateral extension of copper and gold mineralization to the northeast, as well as to the north, east and southeast. The lower grades encountered from 1612m to the end of hole at 1672.76m are interpreted to reflect the drill hole exiting the mineralized system on its southwest side (refer Figure 2).

Table 1 - Hole 7 Assay Results

Previously reported and final assays of intersections from Hole 7, which is located on the southwest margin of the Central Magnetic Feature at Alpala.

Hole 8

Hole 8 has been sited on the same drill pad as Hole 5 (797185.49 UTME, 83174.94 UTMN, 1608.5 m elevation) and is being drilled with an 85 degree inclination towards UTM (Universal Transverse Mercator) north (Figure 2). Drilling commenced on August 15th and on August 24^th was at a depth of 347 metres.

The hole is targeted to intersect the MVI magnetic anomaly at a point that is approximately 100m north-northeast of the upper contact of the high-grade zone in Hole 5, and at a point approximately 170m north-northeast of the lower contact to the high-grade copper-gold intersection in Hole 5 (Figure 3). The hole will aim to generate a copper-gold intersection at the third apex of a triangle, with Holes 5 and 7 lying along the structurally controlled southwest margin of the MVI magnetic anomaly. Hole 8 is targeted to deliver an intersection within the anomaly 100m to 170m northeast of Hole 5.

IP Survey and Magnetic Modeling

The Orion 3D IP surveying of the Alpala grid commenced on 3 August. In early August an additional 3 Quantec personnel arrived on site to supplement the 13 personnel on site. The additional personnel were flown in to Ecuador by Quantec to optimize survey productivity at Cascabel.

Chargeability, conductivity and resistivity measurements have now been completed for the Alpala grid and this data will now be processed to deliver preliminary "inversion" models.

The Orion IP crew is presently mobilizing equipment from the Alpala grid area to the Aguinaga grid.
The IP survey over the Aguinaga grid covers an area of approximately 4 square kilometres.

Metallurgical Testwork

Preliminary testwork by Inspectorate in Vancouver is well advanced and results are expected before the end of September.

Rio Cachaco Mapping and Sampling Program

Preliminary geological inspection over the southern drainage divide of the Rio Cachaco catchment is underway, and will be followed by geological mapping and soil sampling. The soil sampling survey will extend the current soil sample coverage westward over strong magnetic anomalies that lie under the topographic divide south of Rio Cachaco and 2 kilometres west-northwest of Central Alpala.

Independent Geological Review

Well-known porphyry expert Dr. Steve Garwin carried out an independent review of the Alpala Prospect over a week in late July. This review included a site visit to the Alpala region and a detailed review of the drill core from Alpala, especially Holes 1, 5 and 7. While the project technical team is still reviewing the report, the conclusions of the geological review confirm both the large size and high-grade potential of the Alpala target at Cascabel. The other four porphyry copper (+/- gold) targets within the Cascabel concession, Aguinaga, Moran, Tandayama/America and Chinambicito, were not part of this review (see Figure 1 for location of these targets).

About Cascabel

SolGold Plc owns 85% of the equity of Exploraciones Novomining S.A. ("ENSA"), an Ecuadorean registered company that holds 100% of the Cascabel concession in northern Ecuador. Cornerstone owns the remaining 15% of ENSA, which also holds the rights to the La Encrucijada gold-silver project. SolGold is funding 100% of the exploration at Cascabel and is the operator of the project with Cornerstone Ecuador S.A. providing some exploration and administrative services. Cornerstone's 15% interest is financed through completion of a National Instrument 43-101 compliant feasibility study.

Cascabel is located in north-western Ecuador in an under-explored northern section of the richly endowed Andean Copper Belt, 60 km northeast of the undeveloped inferred resource of 982 million tons at 0.89% Cu Junin copper project. (Mineralization identified at the Cu Junin copper project is not necessarily indicative of the mineralization on the Cascabel Property).

Qualified Person:

Yvan Crepeau, MBA, P.Geo., Cornerstone's Vice President, Exploration and a qualified person in accordance with National Instrument 43-101, is responsible for supervising the exploration program at the Cascabel project for Cornerstone and has reviewed and approved the information contained in this news release.

Logging, sampling and assaying

Holes referred to in this release were or are being drilled using HTW, NTW, NQ and BQ core sizes (respectively 7.1, 5.6, 4.8 and 3.7 cm diameter). Geotechnical measurements such as core recovery, fracturing, rock quality designations (RQD's); specific density and photographic logging are performed systematically prior to assaying. The core is logged, magnetic susceptibility measured and key alteration minerals identified using an on-site portable spectrometer. Core is then sawed in half at Cornerstone's core logging facility and half of the core is delivered by Cornerstone employees for preparation at Acme Analytical Laboratories (ACME) affiliate laboratory in Cuenca. Core samples are prepared crushing 1 kg to 80% passing 2 mm (10 mesh), splitting 250 g and pulverizing to 85% passing 0.075 mm (200 mesh) (ACME code R200-250). Prepared samples are then shipped to ACME in Vancouver, Canada where samples are assayed for a multi-element suite (ACME code 1E, 0.25g split, 4-acid digestion, ICP-ES finish). Over limit results for Ag (> 100 g/t), Cu, Pb and Zn (each one > 1%) are systematically re-assayed (ACME code 7 TD1 or 7 TD2, 4-acid digestion, ICP-ES finish). Gold is assayed using a 30 g split, Fire Assay (FA) and AA or ICP-ES finish (ACME code G601).

Quality assurance / Quality control (QA/QC)

The ACME affiliate preparation facility in Cuenca was audited by Cornerstone prior to the start of the drilling program and ACME is an ISO 9001:2008 qualified assayer that performs and makes available internal assaying controls. Duplicates, certified blanks and standards are systematically used (1 control sample every 15 samples) as part of Cornerstone's QA/QC program. Rejects, a 100 g pulp for each core sample and the remaining half-core are stored for future use and controls.
